To @ZZ whom, il.' img concern:

Beit known th; Y I, FRED EBELING, a citizen of the United Sta As,\residin,f1 at Linn, in the county of Washir'-A ton and State of Kansas, have invented a bootingMachine, as set forth in the auriez-lcd speciiication.

This invention relatesto a machine gun particularly adapted for use on express cars of railroads, and for defending the saine from the attacks of robbers and outlaws. It is capable of use, however, in various other connections, indeed for all purposes to which other guns of tlis class are put.

The object of the invention is to provide a machine having a plurality of barrels, each 'with a separatecartridge carrier and firing mechanism, and the whole combined with means for operating all the parts in unison.

'lo this end the invention consists of a series of gun barrels, each provided at its rear end with a cartridge-carrying disk in which the cartridges are arranged, and combined with spring-actuated firing-pi ns, which are capable of exploding the cartridges as successively 'presented thereto by 'the revolutions of the said disks; and in tr. chanistn for operating the ring-pins simultaneously and in unison with the revolutions of the disks aforesaid.

Referring to the accompanying drawings: Figure 1 represents a plan view of my machine embodied in its preferred form; Fig. 2, a side elevation thereof; Fig. 3, an elevation of the front end thereof; lig. 4, a vertical cross-section of .the machine.

The reference nnmerall indicates the side portions of my machine, which are duplicates of each other and which are rigidly joined by means of the front portion 2, axles 3, and beam 4.

The front portion 2 of the machine projects a considerable distance above the upper edges of the side portions 1, and is rigidly secured thereto; while the axles 3 are two in number and are iixed to the lower. edges of the side portions 1 by means of the boxes 5. Mounted upon the axles 3 are the grooved carrying- -wheels'6, which are two for each axle and which are designed to travel upon the track 7, as may be seen by reference to the drawings, and whereby the machine may be moved. The track 7 may be a track laid in the express car, or at any place where it is desired to use the machine.

Revolublyjournaled in the upper end of the front portion 2, and in the beam 4, are the drums or shafts 8 and 9, which are two in number and which are provided with reduced portions or trunnions 10, by which their mounting is effected. The drum or shaft 8 extends only between the end portion 2 and beam 4, while the drum 9 is extended or pro-A vided with an auxiliaryv drum 11, projecting rearward of the beam 4. 11 has no bearing at its rear end; and is re- .duced or provided with a smaller and axially- This drum or shaft coincident shaft 12 at said rearend. The

shaft 12 carries a worm 13, which operates as will be hereinafter. described.

14 indicates three shafts, which project out transversely from the left-hand side por tion 1, and which have the respective car tridge-carrying -gears 15 revolubly mounted l thereon. The gears 15 are three in number and are each formed with the cartridge-receiving openings 16. These openings are arranged in circles in each gear, and thege'ars are so adjusted that as they revolve their respective openings 16 will register with the bores 17 of the gun-barrels 18. The gun-barrels 18 are one for each of. the gears 15, and are provided, at their inner ends, with rearwardly-odset arms4 19, by which they are secured to the upper edges of the side portion 1, to which the gears 15 are attached, screws -or other fastening devices 20 being provided whereby to eifect the fastening.

21 indicates a longitudinal bar, which serves as a bearing or support for the outer ends of the shafts 14, which are'held in place by means of the brackets 22, vlocated one at each of'its ends. The brackets 22 are removably secured in place by screws 23, and the urpose of their removable mounting wil be hereinafter explained. The mechanism for exploding the cartridges used in the machine consists of three vertical spring-plates 23, secured to the inner and lower sides of the side portions 1, by means of the screws 24 and clamping staples 25. These plates are located one opposite each of the gears 15, and have formed integraltherewith the tiring-pins 26, which are adapted to be arranged in openings S and 9 are projected forward of the front portion 2, 'and there provided with "the iixed gears 29, which mesh with each other and which are provided to effect the transmission of motion from the shaft or drum 9 to the shaft or drum 8, acrank-arm 30 being'atiixed to the, shaft or drum 9 by which motionjis primarily imparted thereto. The worm 13 meshes with a gear 31, fixed to a transverse shaft- 32, journaled in turn in the rear ends o f the side portions l.

The right-hand end of the shaft 32 is provided with a spur-gear 33, which meshes with the rear gear of the three gears 34. These gears 3st are respectively journaled upon the shafts 35 of the right-hand side portion 1, a bar 36 and brackets 37 being provided and operating as the bar 21 and brackets 22 of the opposite side of the machine. This right-hand side of the machine, with its gears and associated parts, is intended to be equipped with l mechanism similar to thatsupplicd to the lefthand side. It is not shown, however,since the construction of the left-hand side as shown in the drawings will fully reveal the nature thereof.

In the operation of my invention the openings 1G in the gears 15 should be provided each with a cartridge. This is to be effected by removing the barrels 18 and brackets 22,

whereupon it will be'possible to slide the gears 1 5 oit the shafts 14, thus putting them in position to be filled with cartridges. When this' is done, the parts should be replaced and the machine will then be ready for operation. The cartridges are tired by applying av rotary movement to the shaft 9, which will result in an engagement of the stu'ds or arms 2S with the spring-plates 23, thus drawing them back momentarily and allowing them to spring forward when released, thus throwing the tiringpins 26 into engagement with the respective cartridges and firing the same, the bullets thereof passing out through the bores l?, of the b arrels 18. Simultaneously with this operation the gears 15 will be revolved through the medium of the gear 38, fixed to the let'th and end cfv the shaft 32, and meshing with the rear gear 15. This revolution of the gears -15 will successively place each opening 16 thereof apposite the corresponding openings or bores 17 of the barrels 18, thus placing the contiguous Acartridge in position to be exploded after the preceding cartridge has been so acted upon.

It will be understood that the gears and other motion-transmitting parts of my mal chine will be so adjusted that the parts will operate with the necessary regularity and regulation. Thus, it is essential that each spending opening 1G immediately after the cartridge thereof has been exploded, and that said pin be allowed to fall back as soon as the contiguous opening 1G is opposite the pin, the revolution of` the geary 15, during the iuterim, ,being snfieient to place the next open- 'ing 16 in position.

at the right-hand side thereof will'operate similarly to the operation just described, and this through the medium of the worm 13 and shaft 32, as explained. The machine is mounted upon the track 7 so as to facilitate moving it during the firing operation, thus making it possible for the machine to be given a larger range than ordinarily. This movement will be a substitute for the vibratory movement imparted to the barrel of the well-known Gatling gun.

minor details of construction may be resorted to without departing from the principle or sacriiicing any of the advantages of this invention.

llaving thus described the invention, I claim- 1. 'lhe combination of a gun barrel, a disk axially mounted adjacent to the rear end thereof and p"ovided with means for imparting a rotary movement to it, the said disk having a series of cartridge-receiving openings therein, said openings being capable of respectively registering with the bore of thegn barrel,a spring-plate provided with a.

be capable of movement in a line longitudinally with the gun barrel and directly toward the rear end thereof, and a revoluble shaft having studs thereon for swinging said springplate and thereby causing the firing-pin to explode the cartridges placed in the path thereof, substantially as described.
